Memory card adapter
A memory card adapter includes a cover, a base, a connecting apparatus and a flexible strip. An inserting groove is formed between the cover and the base. Two retaining walls are arranged in two sides of the base. An opening is opened in the retaining wall and connects the inserting groove. The connecting apparatus is fixed in the rear of the base. The flexible strip includes a main part showing a strip shape, an extending end formed in the front end of the main part and against the outside of the retaining wall, and a bending portion formed between the main part and the extending end and protruding into the inserting groove from the opening of the retaining wall. The flexible strip can fasten a Micro SD card in the memory card adapter firmly, while the Micro SD card is inserted.

1. Field of the Invention
This present invention relates to an adapter, and more specifically to a memory card adapter, by which a Micro SD card can be read by a standard memory card interface.
2. The Related Art
As the volume of the electrical product decreasing, a small size memory card is used in the electrical product more and more, such as Mini SD card and Micro SD card. The small size memory card cannot deliver information stored in the memory card into the electrical product by a traditional memory card connector. The small size memory card must be transformed into the SD card standard by a card adapter to deliver information. For the small volume of the small size memory card, while the small size memory card is inserted into the card adapter, the small size memory card is not located in the card adapter, as a result the signal is not delivered stably between the small size memory card and the card adapter.
U.S. Pub. NO. 2007/0026740 discloses an adapter card structure. The adapter card structure is used for adapting a Mini SD/Micro SD card to a SD card. A casing is opened in the adapter card structure, a stick is formed in the side of the casing. While the Mini SD/Micro SD card is inserted into the adapter card structure, the Mini SD/Micro SD card can be latched firmly in the adapter card structure for a projection part formed in the tail end of the stick against a notch opened at an edge of the Mini SD/Micro SD card.
Because the stick is ejected with the casing of the adapter card structure, the stick is not easily manufactured, and the volume of the casing is smaller, the casing is not easily manufactured also.
SUMMARY OF THE INVENTIONAn object of the invention is to provide a memory card adapter comprising a cover, a base, a connecting apparatus and a flexible strip. A first rectangular space is opened in the middle of the cover. A right and left retaining walls are arranged symmetrically in two sides of the base, a second rectangular space is defined between the retaining walls. An incline is arranged in the second rectangular space and vertical to the retaining walls. The first and second rectangular spaces define an inserting groove to accept an outer memory card. An opening is opened in right retaining wall and connects the inserting groove. The connecting apparatus includes a housing and a plurality of electrical terminals arranged in the housing. The connecting apparatus is fixed in the rear of the base. The front ends of the electrical terminals are located in the rear of the incline. The flexible strip includes a main part showing a strip shape, an extending end formed in the front end of the main part and against the outside of the right retaining wall, and a bending portion formed between the main part and the extending end and protruding into the inserting groove from the opening of the right retaining wall.
As above description, the flexible strip can fasten a Micro SD card in the memory card adapter firmly, while the Micro SD card is inserted into the memory card adapter, and for the incline design, the Micro SD card will not destroy the electrical terminals in the memory card adapter while the Micro SD card is pushed into the memory card adapter.
The invention, together with its objects and the advantages thereof may be best understood by reference to the following description taken in conjunction with the accompanying drawings, in which:
First referring to
The base 20 defines a second rectangular space in the middle thereof. A plurality of projections 201 are arranged in two sides of the base 20 and accord to the grooves 101 in the cover 10. In
